The Oscar-winning actress is widely regarded as one of Hollywood's most down-to-earth stars, but Jennifer freely concedes that her attitude towards people changes as soon as she's in a public space.

Speaking to Adam Sandler for Variety magazine's Actors on Actors series, Jennifer explained: ''Once I enter a public place I become incredibly rude, I turn into a huge ass.

''That's kind of like my only way of defending myself [from fan attention].''

During their chat, the 27-year-old actress demonstrated her icy glare and finger wag, which she uses when fans approach her in public.

She revealed too, that she has no qualms about declining to pose for selfies with her fans.

Jennifer said: ''That's like my only defence. One of my best friends is Amy Schumer. I take my dog to the park all the time, Central Park. As soon as I meet her in the park, we're f***ed.''

Meanwhile, Jennifer previously claimed that people pay too much attention to her and what she's doing with her life.

The 'Mother!' star believes she is understood by the public, but she thinks they ought to find other things to interest themselves with, rather than focusing on her career and personal life.

She said in 2016: ''I don't feel like I'm misunderstood. I feel like I'm over-paid-attention-to.

''I'm not trying to be a GIF. I'm not trying to be a picked-up-on-Twitter quote. All I'm trying to do is act. And I have to promote these movies. And I am, at the end of the day, I guess, a f***ing lunatic. So if you record what I'm saying, it's gonna be goofy.

''What do I do? What do I do? I'm just a girl, sitting in front of the world and asking them to forgive her for speaking.''
